A Guerrilla is a soldier who engages in irregular or 'guerrilla' warfare. The term came into use in 19th Century Spain to describe peasants who fought Napoleonic invaders using sabotage, hit and run, night attacks and other unconventional tactics. Guerrillas specialize in stealthy lightning raids, hitting and damaging the invading enemy quickly and then fading into the countryside before the larger but slower opponent can retaliate.

Commanding the destroyer to attack a defending unit will cause it to use a handgun to fight the designated defender. This also happens when all defensive buildings are destroyed and will cause the destroyer to fight back when attacked by enemy troops.
